MACHINE FOR FLANGING THE COUNTERS OF BOOTS-AND SHOES.

SPECIFICATION forming part of Letters Patent No. 243,917', dated July 5, 1881.

Application tiled April 4, 1881.

To all whom it may concern:

Be it known that we, RUEUs H. HURL- BUT, of Sudbury, in the county of Middlesex, and CHARLES E. KENNARD, of Boston, in the county of Suffolk, and both of the State of Massachusetts, have invented a new and useful Improvementin Machines for Flanging the Counters of Boots and Shoes, of which the following is a specification.

Our invention relates to that class of machines in which the main part or body of the counter to be langed is held by a suitable clamping apparatus rmly about a heel-shaped former, while a projecting edge of the counter` is turned over upon the sole or tread surface of such former and forms the liange of the counter.

The object of our invention is to provide a simple and effectual means for clamping the counter` about the former, and also a flangeturning device, which shall not only turn down such flange, but subject it to a continued rubbing action, thereby causing it to retain its new form much better than when simply turned by a reciprocating slide, as is usually done,

and also leave it more free from wrinkles.

While our invention is primarily designed for fianging the counters or heel portions of the uppers of boots and shoes preparatory to lasting the same, it may with equal facility be applied to counter-stiienings before they are turn down the ange and at the same time repeatedly rub the same in the direction of its length, as hereinafter set forth.

In the accompanying` drawings, Figure l is a perspective of a machine embodying our invention 5 Fig. 2, a view of the same with portions removed to show the flan ging device and its operative mechanism, and Fig. 3 a longi tudinal section.

(No model.)

Similar letters refer-to similar of the figures.

A represents the frame of the machine, upon whichisbolted'the stand B,supporting the upright way a., upon which the slide O is adapted to be reeiproeated, being drawn down by the rod c, attached to a treadle, b, having its fulerum at d.

f is a spring adapted to support the slide O in the position shown in Fig. l and to yield to pressure brought to bear upon the treadle b sufficiently to allow the requisite motion of the slide.

D is the former or male mold, whichis bolted firmly to the slide C.

E is a clamping-strap or female mold, supported near each end by the arms g g, which are pivoted at their opposite ends to the ends of a yoke, h. -These armsincline upward and toward each other from each end of the yoke, as shown, and when the ends attached to the strap are carried downward by the movement of the strap they will approach each other and thrust the ends of the strap inward, as will be readily seen. This yoke h may be made flexible, if desired; but we prefer to make it rigid and attach it at its center to the upright rod t', which is adapted to slide in bearings, as shown, and is pressed upward to its normal position by the spring la.

Directly inthe rear of the clamping-strap E is a notched plate, F, which is mounted upon the end of the shaft m, which rests in bearings a n upon the frame of the machine. (See Fig. 2.) Upon this shaft m is fastened awheel, Gr, carrying apin,p, upon which is pivoted one end of a connecting-rod, o, the other end of which is attached to the eccentric-strap H, which is operated by the inelosed eccentric K upon the drivin g-shaft L, which receives its motion from the pulley M. It will be readily seen that as the shaft L is revolved the eccentricKwill, through the strap H, rod o, and wheel G, impart to the shaft m a vibratory motion about its center, which is shared by the plate F.

In the rear of the lower end of the former D is an adjustable gage, s, which is a plate of metal having its front end bent upward, as shown in Figs. Zand 3, and fastened by screws parts in each to the frame of the machine, and which, by its adjustment, serves to determine the distance which the edge of the counter1 shall project beyond the rear face of the former, and consequently the wid th of the flange to be turned.

At the rear end ofthe shaft fm, Fig. 3, is a plate of rubber, t, placed between two plates of metal, against one of which presses the end of the shaft m, and against the other the setscrew fv, which is threaded in a boss attached to the frame of the machine. This rubber allows the shaft m to yield slightly to end pressure upon the surface of the plate F, and thus accommodate the varyin g thickness of the flanges of counters. The screw o serves to adjust the pressure as may be required.

W, Fig. 3, represents a shoe-upper in position to be operated upon, showing the flange of the counter or heel portion of such upper turned down upon the inner surface of the former and in position to be rubbed by the surface of the vibratory plate F.

Instead of the strap E, an equivalent device consisting of a mold made of several parts hinged together may be used, if desired.

The operation of the machine is as follows A counter, being placed around the lower part of the former D, is thrust inward until its edge strikes the gage s. The treadle b being depressed by the foot of the operator, the former is drawn down upon the central portion of the strap or mold E, which, being depressed, has its ends thrown in close against the former by the action of the armsg g. The counter, thus held firmly about the former, is by its continued downward movement carried past the notched plate F, which, by the rotation of the shaft L, is rapidly vibrating about its central axis. The projecting edge of the counter is turned down by the sides of the notch in the plate F, and its circular vibratory movement rubs the flange in the direction of its length while being turned, thus insuring a smooth and permanentflange or heel-seat.

We claiml. The combination of the reciprocating former D with the clamping-strap E, supported by the arms g g, and yoke h, substantially as shown and described.

2. In a machine for langing counters, the vibratory notched plate F, as and for the purpose specified.

3. The combination ot' the reciprocating former D with the clamping-strap E, arms g g, yoke h, and rod t', substantially as shown.

4. In a machine for Hanging counters, the anging-plate F, mounted on avibratory shaft, m, in combination with a yielding plate, t, and set-screw v, substantially as specified.

5. The combination, with the former or male die D, with means for holding a counter rmly about it, of the vibratory notched plate F, arranged and to operate substantially as described.

6. The combination ot' the former D, clamping-strap E, plate F, and gage s, as herein set forth.
